Question

我的任务是在Django中从1.5迁移到2.1。我目前在我的环境中使用Python 3.6.2。追溯如下：

(my_env) My-MBP:mysite my_mbp$ python manage.py runserver
Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x10d82b598>
Traceback (most recent call last):

    apps.populate(settings.INSTALLED_APPS)
  File "/Users/my_mbp/Software/Environments/my_env/lib/python3.6/site-packages/django/apps/registry.py", line 81, in populate
    raise RuntimeError("populate() isn't reentrant")
RuntimeError: populate() isn't reentrant

由于回溯似乎是指站点程序包，因此我难以识别导致错误的代码中的内容。通过阅读其他文章，它似乎与wsgi有关，但我不知道确切是什么。这是我当前的wsgi设置：

 import os
    import sys
    import site

    ## Add the site-packages of the chosen virtualenv to work with
    site.addsitedir('/Users/my_mbp/Software/Environments/my_env/lib/python3.6/site-packages')

    ## Add the app's directory to the PYTHONPATH
    sys.path.append('/Users/my_mbp/Software/project/mysite')
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

    ## Activate your virtual env
    activate_env=os.path.expanduser("/Users/my_mbp/Software/Environments/my_env/bin/activate_this.py")
    #execfile(activate_env, dict(__file__=activate_env))
    with open(activate_env) as f:
        code = compile(f.read(), activate_env, 'exec')
        #exec(code, global_vars, local_vars)
        exec(code)

    # This application object is used by any WSGI server configured to use this
    # file. This includes Django's development server, if the WSGI_APPLICATION
    # setting points here.
    from django.core.wsgi import get_wsgi_application
    application = get_wsgi_application()

要添加的另一件事是，当我在INSTALLED_APPS中将应用程序注释掉时，这会产生另一条错误消息：

RuntimeError: Model class myapp.models.Mail doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
